Herpesvirus reactivation is common after liver transplantation.ObjectiveAnalyze the presence of cytomegalovirus (HCMV) and human herpesvirus-6 (HHV-6) DNA in liver donor biopsies, seeking to better understand issues involving human donor leukocyte antigens (HLA)-A, B and DR, as well as correlations with acute cellular rejection.MethodsFifty-nine liver transplantation patients were investigated for the presence of HCMV and HHV-6 DNA in liver donor biopsies, using the Nested-PCR technique. The clinical donor information and HLA matches were obtained from the São Paulo State Transplant System. The recipients’ records regarding acute cellular rejection were studied.ResultsSeven (11.8%) biopsies were positive for HCMV DNA and 29 (49%) were positive for HHV-6 DNA. In 14 donors with HLA-DR 15 nine had HHV-6 DNA positive liver biopsy with a tendency for significant association (p = 0.09), 22 recipients developed acute cellular rejection and 9/22 were positive for HLA-DR 15 (p = 0.03; χ2 = 4.51), which was statistically significant in univariate analysis and showed a tendency after multivariate analysis (p = 0.08).ConclusionHHV-6 DNA was prevalent in liver donors studied as well as HLA-DR 15. These findings suggest that patients with HLA-DR 15 in liver donor biopsies develop more rejection after liver transplantation.
